Integrated into release/v3.8.43

 - **Security hardening follow-ups (v3.8.15):** the `auth_token` cookie now sets an explicit 30-day `maxAge` so sessions persist as intended (Seg3); the management bootstrap warns at boot when `INITIAL_PASSWORD` is left at the insecure `CHANGEME` default (Seg2); VS Code path-token endpoints (`/api/v1/vscode/raw/[token]`) emit a once-per-process security warning since the API key travels in the URL and can leak via logs/proxies (Seg4); the system version route resolves the real global install path via `npm root -g` instead of a hardcoded `/app` (Bug3); and auto-update mode detection segment-matches `node_modules` instead of substring-matching, eliminating false "global install" positives (Bug1).
 
+- **fix(cli):** rename the Node process title to `omniroute` so it shows correctly in ps/htop. (thanks @waguriagentic)
